Description
The LH1529A and LH1529B Telecom switches con-
sist of an optically coupled solid state relay (SSR) and
bidirectional input optocoupler. The SSR is ideal for
performing switch hook and dial-pulse switching while
optocoupler performs ring detection and loop current
sensing functions. Both the SSR and optocoupler pro-
vide 5300 V
